Better than White Elephant filters. Not as good as Big Ben filters. Peterson's Deluxe system does it all no tar in the stem all in the trap.
Work great in my pipe. Smooths out the smoke without removing the flavor.
Easy to use and change often.
For pipes calling for the 9mm, these fit nicely.
Great Filter - can use twice forwards or backward. After using the sides do not expand like other brads. A little pricy but worth it.
